Description

Technical Field

[0002] A quantitative structure generally refers to a system or design that can precisely control the flow and distribution of materials during the production or processing process. It ensures a consistent amount of material is screened or processed each time, and is usually achieved through sensors, control systems, or specific feeding equipment. The horizontal airflow screener is a high-precision screening device for mesh screening of fine powders. It is widely used in the metallurgy, mining, pharmaceutical, food, chemical, metal powder, and non-metal industries. After passing through a screw conveyor, the material is mixed with the airflow and atomized into a mesh cylinder. The impeller blades inside the mesh cylinder simultaneously subject the material to centrifugal force and cyclonic propulsion, ejecting it from the screen and collecting it through the fine material outlet. Large particles are intercepted and transported along the cylinder wall to the coarse material outlet.

[0003] The existing horizontal screening machine is supported by a frame to provide stability and durability. The screen box is the core part of the horizontal screening machine, which is usually welded from steel plates and has a screen inside. The part used for screening is usually woven from metal wire. However, when grading and removing impurities from materials, the screen is often blocked, affecting the normal screening operation. Therefore, a horizontal screening machine with a quantitative structure is proposed to solve the above problem. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

One end of the first spring 13 is fixedly connected to the side wall of the second connecting plate 11, and the other end of the first spring 13 is fixedly connected to the side wall of the brush 14. The side wall of the box body 2 is fixedly connected with a fan 15, and the side wall of the fan 15 is fixedly connected with a coarse material pipe 16. The side wall of the box body 2 is fixedly connected with a fine material pipe 17. The conveying assembly includes a conveying pipe 4, an auger 5 and a feed pipe 6. The side wall of the conveying pipe 4 is fixedly connected to the side wall of the box body 2, the side wall of the auger 5 is rotatably connected to the inside of the conveying pipe 4, and the side wall of the feed pipe 6 is fixedly connected to the side wall of the conveying pipe 4;

[0032] When using this equipment, first start the first motor 3 to rotate the auger 5, and then transport the material into the conveying pipe 4 through the feed pipe 6. Then the auger 5 transports the material to the inside of the screen frame 7. At the same time, the start of the fan 15 plays a role in blowing wind, prompting the material to pass through the screen frame 7 smoothly for screening. During screening, the rotation of the rotating shaft 8 drives the scraper 10 to rotate, and the rotation of the scraper 10 evenly distributes the material on the screen frame 7. At the same time, the rotation of the rotating shaft 8 drives the brush 14 to rotate, and cleans up the material blocking the mesh holes of the screen frame 7 to avoid clogging the mesh holes and affecting screening. At the same time, a telescopic rod 12 is fixed between the second connecting plate 11 and the brush 14. The telescopic rod 12 can guide the relative movement between the brush 14 and the screen frame 7. At the same time, the first spring 13 makes the brush 14 fit with the screen frame 7, thereby improving the screening efficiency. The screened materials are discharged from the coarse material pipe 16 and the fine material pipe 17 respectively.

[0033] Reference Figure 2 and Figure 4The side wall of the fine material tube 17 is fixedly connected with a connecting frame 18, which plays a role of fixed connection. The connecting frame 18 and the side wall of the fine material tube 17 are fixedly connected with a fixed block 19. A second spring 20 is fixedly connected between the fixed blocks 19. The internal rotation of the connecting frame 18 is connected to an eccentric wheel 21. The side wall of the eccentric wheel 21 is connected to a connecting rod 22 for driving the connecting rod 23 to move. The side wall of the connecting rod 22 is fixedly connected to the connecting rod 23. The side wall of the fine material tube 17 is fixedly connected to the connecting rod 23. Connecting column 26, the interior of connecting column 26 is fixedly connected to round rod 24, and the side wall of round rod 24 is sleeved with third spring 25, and the third spring 25 is used for rebound reset, and one end of the third spring 25 is fixedly connected to the side wall of round rod 24, and round rod 24 is used to hit the pipe, and the other end of the third spring 25 is fixedly connected to the interior of connecting rod 23, and the side wall of connecting rod 23 is slidably connected to the interior of connecting column 26, and the side wall of connecting frame 18 is provided with second motor 27, and the output end of second motor 27 is connected to eccentric wheel 21;

[0034] After the material is screened, the coarse material is discharged through the coarse material pipe 16, and the fine material is discharged through the fine material pipe 17. In order to prevent the material from being blocked in the pipeline, it is necessary to start the second motor 27 to make the eccentric wheel 21 start to rotate. The rotation of the eccentric wheel 21 drives the connecting rod 22 to swing back and forth, and the connecting rod 22 will make the fixed connecting rod 23 hit the round rod 24 forward, causing the third spring 25 to contract. Due to the rotation of the eccentric wheel 21, a certain height difference will be generated, which will cause the second spring 20 fixed between the fixed blocks 19 to compress and stretch. At the same time, the round rod 24 hits the inside of the connecting column 26. The collision of the round rod 24 causes the pipeline to be in a vibrating state, effectively preventing the material from being blocked inside the coarse material pipe 16 and the fine material pipe 17.

[0035] Working principle: When using the equipment, start the first motor 3 to rotate the auger 5, and transport the material transported from the feed pipe 6 into the conveying pipe 4 to the inside of the screen frame 7. The fan 15 plays the role of blowing wind, prompting the material to pass through the screen frame 7 smoothly for screening. At the same time, the rotation of the rotating shaft 8 drives the scraper 10 to rotate. The rotation of the scraper 10 makes the material evenly distributed on the screen frame 7. At the same time, the brush 14 also rotates to clean up the material blocking the mesh holes of the screen frame 7 to avoid clogging the mesh holes and thereby improve the screening efficiency. At the same time, a telescopic rod 12 is fixed between the second connecting plate 11 and the brush 14. The telescopic rod 12 can guide the relative movement between them. At the same time, the first spring 13 makes the brush 14 fit with the screen frame 7, and the screened material is discharged from the coarse material pipe 16 and the fine material pipe 17.

[0036] After screening, the material is discharged through the coarse material pipe 16 and the fine material pipe 17 respectively. In order to prevent the pipeline from being blocked, the second motor 27 is started at this time, so that the eccentric wheel 21 starts to rotate, and at the same time, it drives the connecting rod 22 to swing back and forth, and the connecting rod 22 causes the fixed connecting rod 23 to hit the round rod 24 forward. Due to a certain height difference generated by the rotation of the eccentric wheel 21, the second spring 20 fixed between the fixed blocks 19 is compressed and stretched, and at the same time, the round rod 24 hits the inside of the connecting column 26, so that the pipeline will be in a vibrating state all the time, effectively preventing the material from being blocked inside the coarse material pipe 16 and the fine material pipe 17.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
